Univ. of Nebraska-Lincoln, Lincoln, NE

Software Development Specialist Aug 1998 – June 2010

--------------------------------------------------------------------------------

Developed, in Perl, web-based front end to MySQL RDBMS for Database Design and

Maintenance (DBDM), using DBD/DBI(http://citnews.unl.edu/DBDM,

password protected, not a public service):

- Crates databases and schemas defined through web interface;

- Maps MySQL fields into HTML web-form fields for data entry and presentation;

- Protects database referential integrity;

- Supports multiple MySQL servers;

- Maintains user authentication and authorization;

- Supports hierarchically organized scrolling lists and drop-down menus;

- Provides context-sensitive help system;

- Keeps history of modifications to database schema;

- Used for the whole of my web production.

Beef Cattle Production website, in Perl (http://beef.unl.edu):

--------------------------------------------------------------

- On customer’s request, generates static pages (using templates and database

contents) for Timely Topics articles, FAQs, Range Beef Cow symposium

proceedings, Nebraska Beef Reports conference proceedings, etc., thus avoiding

subsequent MySQL connections on page delivery, saving more than 200,000 MySQL

connections a month.

- Using Socket, connects to multiple USDA servers and Aurora Coop. server to

fetch current nation-wide ag. prices (Feedstuff, Grains, Hay, Livestock, etc.)

Parses the fetched web pages and, after web scraping of relevant information,

delivers it in beef.unl.edu templates for seamless presentation.

- Contributes contents to related websites, or fetches contents contributed by

related websites. Extensively uses Perl-generated JavaScript for Beef Reports

navigation, and for Trace Minerals calculations in Learning Modules.

(http://beef.unl.edu/learning/needscalculator.shtml).

- Uses Server-Side Includes to maintain website-wide navigation consistency, to

deliver home-page contents, etc.

- CSS classes for consistent contents presentation.

- On each new article or FAQ submission, combines 20 most recently published

articles/FAQs and delivers them as an RSS feed.

Veterinary Extension, in Perl (http://vetext.unl.edu):

Same concept as http://beef.unl.edu.

------------------------------------------------------

- Graphing with GD.pm (http://vetext.unl.edu/diseaseDetection.shtml)

Animal Science related websites’ database synchronization

---------------------------------------------------------

- ANSCI_Synch.pm Perl Module (Object Oriented Perl).

- Synchronizes Timely Topics, FAQs, visitor’s comments, authors.

- Scalable, involves ANSCI_Lock.pm for database locking.

- Extensive usage of prepared SQL queries.

- Database handles swapping to reduce re-connecting need.

IANR News, in Perl (http://ianrnews.unl.edu)

--------------------------------------------

- Eleven years archive, organized for browsing by category, publishing date,

monthly production (month/year), or by title.

- On new article submission, creates RSS, ATOM, JavaScript news feeds.

JavaScript feed created 11 years ago, when majority of consumers were not

aware of RSS or ATOM formats, but is still consumed by some commercial

websites (ex: http://midwestmessenger.com, under News tab).

- As in my other websites, FTPs newly-created static pages to Netscape

Enterprise server for indexing, using Net::FTP Perl module.

- On request, converts articles from HTML to PDF format.
